Margo, I decided to go visual. I looked up photos of what the flower was to look like on each orchid I own, some shots I have taken of them in bloom and formed a booklet that I printed out for myself. I write down when each flowers so I will know when to expect blooms the following years, and if there is a scent. I write down parentage, when I bought the plant, from whom I bought the plant and what the cost was. This information went into a 3 ring binder by genus. The Cattleya section is the largest in the notebook, but Miltonias may just catch up to them some day!
